Keith is correct. There is an occasion where three passes are needed. 
When a hot link description includes a page number (\n[%]) if the 
expansion to the text before this point causes it to move to the next page 
the descriptive text, collected on the first pass, will be out of date. So a 
third pass is necessary.

And the command becomes:-

groff -Tpdf -dPDF.EXPORT=1 -z $cmdstring 2>&1 | grep '^\.ds' | \
groff -Tpdf -dPDF.EXPORT=1 -z - $cmdstring 2>&1 | grep '^\.ds' | \
groff -Tpdf - $preconv $cmdstring
